To all whom it may concern Be it known that 1, ll llarnnw B. MORGAN, acitizen of'thc United States, residing at Cleveland Heights, in thecounty of Guya- 5 hoga and State of Ohio, have invented a certain newand useful Improvement in Track-Belts, of which the following is a full.clear and exact descri )tion. 4 a

r I I 9 This invention relates to endless track ing tractors. ,Theobjectof the invention is to produce a serviceable track belt at aminimum cost. The invention consists in a track belt consisting of unitsor links constructed, and connected together substantially as shown inthe drawings and hereinafter described as pointed out definitely in theappended claims.

In the drawing, Figure 'l is a plan view of two connected links of atrack belt which embodies the invention; Fig. 2 is, a side elevation ofthe same two track links; Fig. 3 is a front elevation of one of saidlinks; Fig. 4: is a transverse vertical section in the plane of. line Hon Fig. 2; Fig. 5 is a plan view of the blank from which the top memberof each link is formed; Fig. 6 is a side elevation of a link whichembodies the invention but is slightly different in some 3Q respectsfrom that shown in the preceding I at) to the front and rearends of theplates The figures; Fig. 7 is a front elevation ofthe link shown in Fig.6.

Each of the links consists of two men! bers formed by cutting andbending sheet metal plates. These two members are a top member 10, and afoot 20.

Each top member, when completed, coinprises as integral parts twoparallel side members 12 a transversely cylindrical front an member ll,and a transversely extended eye lindrical rear member 15. M

To produce this top member, a flat and substantially rectangular metalplate is employed. '(See Fig. 5.) The middle partof as this platebetween them-two side members 12 is punched out, forming a centralrectangular opening, but some [or the metal so punched out is left inthe form of .two

for use as parts of track lay-v rnacit entr.

enough for all practical purposes. The rear tongue and the rear end ofthe plateto which the tongue is attached are then bent to form the largecylinder 15. This'cylinder is not complete, as shown, but itis completeenough for all practical purposes. The 'nietal of which it is formed isbent both below and above the plane in which "width of the top 'member.'

the side members 12 lie; and, in bending the metal to form this largecylinder, said metal is bent around the front cylinder of an adjacentlink thereby hinging the links to gether. The small cylinder serves asthe hinge pintle, and the large cylinder as the sleeve in which said'pintle is rotatably The foot member 20 includes a bottom plate or shoe21, having two turned'up sides 22. The width ofthe shoe of thisfoot ofthe top member, and therefore these sides extend upwardly at aninclination toward each other, while at their upper ends the distancebetween is substantially equal to the The extreme edges of theseupturned sides are bent into horizontal position, thereby forminghorizontalflanges 23 which go beneath and are secured preferably bywelding to the sides of the top of the-top member.

The front end of the shoe or bottom plate of the front member is bentdownwardly to form a round engaging transverse member is preferablygreater than the width grouser 25. T his ispreferably in the form a of aloop, the extreme end 26 ofwhich passes beneath and'is welded orotherwise secured to the. lower face of the shoe 21.

When a'belt is made of members constructed as shown and described,andwhen these links are connected together in suf- 4 ficient hu'mbertoform an endless" chain, this chain is admirably adapted for use as a.track belt upon a track layingtractor.

Theside members 12 of the successive links lie in the same plane, andthere is only a small gap between their adjacent ends,-

tongues which remain'attached respectively front ton ueand the front endof the plate of the plate, and into'approrimately cylindrical {form toform the small frohteylin' These side 'meinbers therefore serve as therails for the weight-supporting rollers or, wheels of the'tractor toride on. The central opening in this plate permits the teeth of thesprocket wheels of the tractor to engagetheexternal surface of'the rearcyl ind e l5.

It will be understood that it is not necessary that the downturned frontend of the shoe of each link shall be in loop form, as shown in Fig. 2.It may be simply a downturned flange as shown in Fig. (3, and thisdownturned flange may or may not be reinforced, as shown in Fig. 6. Itwill also be understood that it is not essential that the edges of theupturned side members ot' the front pass beneath the sides of the topmembers, as shown in Fig. 4:, although this is the preferableconstruction of these side members. They may have their upper edgesengaging with the edge of the upper member, and these engaging edges maybe beveled and welded together substantially as shown in Figs. (3 and 7.

Having described my invention. I claim 1. A track belt for track layingtractors comprising a plurality of pivotally connect-' end of themember, each of the smaller cyl-' inders being embraced by and rotatablewithin the larger cylinder of the next adjacent link. 7

parallel flat side bars and 2. A track belt for track laying tractorscomprising a plurality of pivotally connected links, each of whichcomprises an open rectangular top member having two parallel flat sidebars and cylindrical cross bars of different diameters extending betweenthe side bars at the front and rear ends of said top member, and a footmember having upturned sides which engage with and aresecured tothe sidebars of the top members, the small cylindrical cross bar of each linkbeing embraced by and rotatable within the large cylindrical cross barof the next adjacent link.

3, A tr-ack belt for track laying tractors, comprising a plurality ofpivotally connected links, each of which comprises an open rectangulartop member having two cylindrical cross bars of different diametersextending between the side barsat the front and rear ends of said topmember, and a foot member having 11 )turned sides which alon their to t!upper edges are bent into horizontal position and are extended beneathand are secured to the side bars of the top member, the smallcylindrical cross bar of each link being embraced by and rotatablewithin the large cylindrical cross bar of the next adjacent link.

In testimony whereof, I hereunto afiix my gnatu re.
